tapset::task_time − systemtap task_time tapset
Task time query
and utility functions provide information about
the time resource usage of the current task. These functions
provide
information about the user time and system time of the
current
task. And provide utility functions to turn the reported
times
into miliseconds and create human readable string
representations
of task time used. The reported times are approximates and
should
be used for "coarse grained" measurements only.
The reported user
and system time are only for the current task, not for the
process
as a whole nor of any time spend by children of the current
task.
